GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 413,283, dated October 22, 1889.

- Application filed December 28, 1888. Serial No. 294,831. (No model.)

of Pennsylvania, have invented an Improvement in Grain-Binders, of which the following is a specification.

My invention has reference to grain-binders; and it consists of certain improvements,

all of which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

In carrying out my invention I provide the needle-head with the looper and cause it in 7 its rotation about an axis to pick up the cord,

pass it around the bundle,and deliver such cord at a point between the looper and spool to the cord-holder, whereby when the bound bundle is discharged with its binding-cord the then free end of the cord is held in the cord-holder ready for the next bundle. The

needle-head passes through suitable segw In my invention the cord-holder is made movable, and is carried with the progressive movement of the needle-head, and its travel is commensurate with the movement of the needle-head. The cord-holder moves up close to the looper in the needle-head, and is provided with a hook, which travels through a groove on said looper for the purpose of freeing the loop from the looper and pushing the knot close up to the bundle. Working in conjunction with the needle-head and cordholder is a cord-gatherer, the function of which is to bring the cords forming the terminals of theloop around the bundle together and in position to be. properly acted on by the looper, the said cord-gathering device being automatically moved out of the way by the cords in the custody of the needle-head after the looper has made its revolution, so

as to make room for the approach of the cordholder and its cord-cutter toward the looper.

This binder may be used on various makes of machines; but for simplicity I have shown it on a gleaner and binder. It may be provided with asuitable grain or bundle compressing device to assist, in compressing the bundle and relieve the binding-cord from eX- cessive tension until afterthe knot has been tied and the bundle is bound or ready for delivery.

The mere details of my invention may be modified or varied in many ways to suit the ideas of mechanics without departing from the spirit of the invention; hence I' do not limit myself to the precise structures shown.

A better understanding of my invention will be had from the accompanying drawings, in which- Figure 1 is a sectional side elevation of a harvesting-machine embodying my invention. Fig. 2 is a side elevation of the needle-arm, head, cord-holder, and operating devices e5:- posed to view prior to tying the knot. Fig. 3

is an inverted view of the covering-plate removed from Fig. 2. Fig. 4 is a similar view 'to that of Fig. 2, showing position of parts after the knot has just been tied and before the cord is liberated from the looper. Fig. 5

is a cross-section of Fig. 2 on line 00 00. Fig.

tween the cord-supply, needle-head, cord .view showing relative cord-connections bekY gatherer, and cord-holder in act of binding The gleaner shown in Fig.1 is a Well known type of machine, and I will not describe it more than to say that the grain is Figs. 16 to 23 are general views,"

picked up by the toothed wheels D and d and elevated between the guides D and d until it reaches the binding devices above. As the grain is pushed up it is packed against the compressor-band e, connected at its upper end to the pivoted arm E and at its lower end to a lever E, hinged to the main frame of the machine and provided with a spring e, to resist its upward movement. As the needlearm A swings down, around, and up, the grain is pressed together between the compressor-band e and the said needle-arm A, and simultaneously the binding-cord is passed around the bundle and tied, as will be fully described. When the bundle is bound and the needle-arm passes upward and over in the act of discharging the bundle, the compressor arm E is lifted, and is free to swing up as the bundle is pushed against it by the needle-arm, opening a channel for the passage of the bound bundle. The needle-arm is secured to a rotating shaft to, which may be operated in any suitable manner.

A is the needle-head, and is of peculiar construction, and contains the rotating looper. The needle-head, in its travel about the shaft a as a center, passes in succession through the segments B and C, the former of which presents the cord to the looper in the head, and the latter of which contains the cord-holder, cord-cutter, cord-gatherer, and means for operating the devices contained in the needle-head and employed in the production of the knot on the cord.

These segments B and O are secured to the frame of the machine, and preferably provide a passage-way for the grain and bound bundle from two points. For instance, in the con struction shown in Fig. 1 the grain is received at the bottom between parts B and O, and the bound bundle is discharged at the top between parts 13 and (1; but it is evident that after the knot is fully tied it is immaterial how the needle-arm may be manipulated to discharge the bound bundle.

The segment Bis simply a slotted guide, through which the needle-head passes. It has a cord-guide b to properly present the cord to the needle-head. It has also a cam projection B, the function of which is to oscillate the jaw of the needle-head so as to raise it above the cord Z, passing through guide I), and cause the cord to pass into the looper in the head. This segment is shown in Figs. 1, 14, and 15. The segment Ois much longer than segmentB. It is slotted atO for the needle-arm. It is shown in Figs. 1, 2,3, 4, 5, 6, and 7. I will refer to it after describing the needle-head.

The needle-head A, which is particularly shown in FigsS to 14, is made pointed to readily pass through the grain, and is recessed or made hollow, as at A,for the looper II. The looper Hhas a shaft 72, journaled longitudinally in the head and provided with the worm-pinion H, Figs. 10 and 11. One side face of the needle-head is cut open to allow the cord to pass in to the looper; but this opening is cov ered with a jaw F, pivoted at f to the head, and having a'tail or rear extension F, by which it may be oscillated. The looper-pinion has two notches H arranged at angles to each other and adapted to receive the pawl G of the block G, pivoted to the head at g and pressed into connection by a spring g. By this means the looper may be locked in either of two positions when not being rotated. The same teeth which rotate the pinion of the looper cause the pawl to be moved to free the pinion. To the outer periphery of the head is a pivoted arm F hinged at f to the head, and adapted to guide the cord between the looper and cord-guide b and insure its proper presentation to the tying devices. This is shown in Figs. 9,10, and 28. The

looper H is of novel construction, and is clearly shown in the various Figs. 8 to 18 and 15 to 21 and 22. It is formed of an integral piece with the notches H and H on one edge backed by a curved flattened part H and formed with the curved groove H leaving the overhanging projection H pointing away from the notch H The utility of this construction will be shown later on.

Referring now to Sheets 1, 2, and 5, we will see the devices contained in the segment 0 and operated by the needle-head and for operating the movable part of the needlehead. The passageway for the head has two sets of teeth 0 and C the former of which cause the pinion H and the looper H to rotate to form the loop, and the latter cause the rotation of the same parts to bring thelooper into position to cast off the loop after the bundle is bound. These teeth are separated at an interval in which the looper is not rotated and during which it is locked in position, while the stripper M of the cord-holder forces the loop over the looper. (See Figs. 19, 20, and 22.) These teeth 0 O are upon one face of the segment 0, while upon the other face is simply a recess 0 and cam-surface c, which latter acts on the rear extension F of the jaw F of the needle-head to open said jaw in receiving the cord end originally held-in the cord-holder. The recess 0 allows the jaws F to close after the cord has been reeeived, and it is thus seen that the whole of the surface in the segment adjacent to the travel of the needle-head, except the recess portion 0 is a cam. The back surface U at the lower part of the segment acts as a cam to operate pivoted arm F to insure the cord leading from the spool being properly presented to thelooper.

N is the cord-gatherer or device for insursented to the looper close together. As shown in Sheet 2, it consists of a pivoted sliding piece N, having the notch n for gathering the cords, and hinged at N to a carriage Q, traveling upon the segment. The forward end of the piece N is provided with a foot 91 which runs upon a guide P, having a projection 19 at its end. The lower end of the piece N below its pivot-joint is extended, as at 41. Now, as the carriage Q moves, the gatherer moves with it, and when end a passes over the end of the guide P the cords may pull the piece N over to the position shown in dotted lines, Fig. 6, and release the cords. To positively insure this tilting action, the extension n will strike thelug p of the guide, and the further movement of the carriage insures the rocking of the piece N to liberate the cords. The carriage Q has an arm q, having on its free end a stop q, av pin r, and roller R. The stop q catches on a lug g on the segment, Fig. 6, the pin 7" works in a reverse curved slot S, having the curved partconcentric with the pivot-point of the cord-holder hinge-arm J, Fig. 2 or 4, and provided with abrupt parts 8 at each end, and the roller R works in the cam-groove J in hinge-arm J of the cord-holder. When this arm J is moved up, its cam causes the pin 1' to move out of 5 into slot S, and then the cord-gatherer can move over its guide, and is so moved by a movement of the arm J and its cam J. At the end of its stroke the cam J again operates on roller R to force the pin r into the part 5 at the other end of the slot S until the cord-holder, with its cord, has returned to its original position and ready for the next bundle.

The cord-holder I is hinged to the hingearm J, as shown, and has at its upper end a roller or pin 2', running in a cam-groove C C 0 Its lower end has the cord-holder devices and cord-cutter. up, the cord-holder is moved up also, and has a peculiar movement, such that its lower part is caused to approach theneedle-head, then move in close juxtaposition with the looper, moving the stripper M through the groove H of the looper, and finally withdrawing the cord-holder from the looper and needle-head. The arm J is moved by the necdle-head through the link J Figs. 2, 4, and 24, one end of which is hinged to the arm J and the other end at 7" is guided in a groove 0 in the segment 0. A spring J 3 presses against the lower end of the link and forces its projection j into the path of the needle-head. The groove 0 is concentric with the axis of the needle'arm for part of its way, and then deviates so as to move the link away from the needle-head and liberate the arm J and the cord-holder. The needle-head has a notch J Fig. 9, which receives the projection j, the spring J 3 simply acting to hold the parts in contact until the end j enters the groove 0 and to admit of the head A forcing its way past the projection j and until such projection is received in its notch.

The cord holder and cutter is shown in Fig. 25, and consists of aframe I, having the head L, formed with teeth Z Z separated by in tervals, Figs. 27 and 28, and a movable frame K, carried on the frame I by guide-rod k and forced in one direction by a spring is. end of this frame K is formedwith a finger As the arm J is moved The Z and a cutter L, Figs. 26 and 28, which enter the spaces in the rear between the parts I. The frame K has a guide-block Z, which fits and slides ina groove Z in the frame I, and the two parts are held together with provision for movement by the keeper Z. The frame K has a roller W, which is caused to come in contact with the camway w in the needlehead and move the cutter and finger back, compressing the spring 7t, and allowing the cord to be pushed up into the holder and in position to be cut. position in the holder andcutter shown in Fig. 28 just prior to the cord-holder fingers -Z moving from the finger Z and cutter L. As

soon as these parts separate the short end of the cord is liberated and the long end of the cord-Z passes up between the fingers Z Z and cutter, and upon their closing the cord is out near the knot and the long end of the cord is heldin the holder ready for the neXtbundle. The bound bundle is then liberated. This holder is also provided with the stripper M, which is made like a hook and sweeps over the looper to strip the loop off the looper simultaneously with the action of grasping the cord in the holder and cutting the cord,

as indicated in Figs. 19, 20, and 22. It will now be understood that the cam part 0 Fig.

2, causes the cord-holder to approach the looper, the cam part 0 to hold the part I while the needle-head pushes the part K back,

and the part 0 to withdraw the cord-holder from the needle-head. i Instead of relying upon gravity to return the cord-holder to its original position, itmay be drawn back by a spring t acting on a rod t, working through a guide ton the segment 0, which is adapted to hold the spring, as shown in Fig. 2.

The operation will now be understood. The cord-holder has one end of the cord Z, and the cord extends back of the cord-gatherer N, thence to the segment B, through the guide I), to the spool T, which may have a tension device T of any suitable construction. The grain being fed up and packed, as before explained, the needle-arm descends, passing through the segment B, picking up the cord. The needle-arm is now passed through the grain, carrying the cord around the bundle,

and then ascends to pass through the segment 0. The relative arrangement of the cord with the c0rd-holder, cord-gatherer, a needle-head, and segment B will then be substantially as shownin Fig. 15. Now, as the needle-head ascends the segment 0, the cam face 0 opens the jaw F and holds it open, and the cam-face U holds the armF in such position that the two cord ends of the bundleloop are caused to extend across the notch H of the looper H. As the needle-head reaches this position the link J 2 engages with it, and

The cord assumes the in its further vupwardmovement it reaches the position shownin Fig. 2, in which it will be seen that the cam J has just liberated the' pin 1- from s, and thus freed the gatheren The cords in the looper will then be as in tively shifted to make a further rotation of Fig. 16. As the needle-head continues ,to move up, the gatherer moves with it until it falls out of the way, Fig. 6, and in such position it is locked by the pin 1" entering the other slots of S, and secured there by cam J, awaiting the return of the cord-holder. The looper H, just prior to the removal of the cord-gatherer, is caused to make one and one-quarter revolution by the teeth and the cord will be shown as in Figs. 17, 18, and 19. About the ending of this rotation of the looper the cord-gatherer is removed. At this time the cord-holder is about to take the second end' of the cord, and the stripper M is about to strip the loop from the looper. A further movement of the needle-head causes the cord-holder to take the other cord end and the stripper M to push the loop over the looper, as shown in Fig. 20. About this time the cam-surface w of the needle-head presses on the roller WV of the cord holder and cutter, (the roller 1 being in cam-groove C and the cord is in condition for being severed.

A further movement insures the complete pushing over of the loop, Fig. 22, by the stripper, and then the roller 1' passes into camgroove 0 relieving the spring is, and the cutter L is forced forward and severs the cord. A further movement of the needlehead causes the looper to make three-quarters of a revolution to free the knot from the hook H of the looper, as shown in Fig. 23. The further movement of the needle-arm carries the bound bundle up and over, discharging it, while the cord-holder returns to its normal position, It will be observed that in the upward rise of the cord-holder the end thereof and stripper entered the needlehead, Fig. 4, and then the link J 2 was drawn out of contact with the head by the curved upper part of the cam c. The subsequent movements of the cord-holder are due to indirect connection with the needle-head and cord on the looper. The cord-holder and looper-stripperare held to the looper by the cords forming the knot, for if it were not for these cords the spring 25 would cause the said holder and stripper to tend to leave the looper. The cords pull the holder and stripper over the looper and supply the necessary cord and by said cords are positively moved and temporarily connected. I would also remark that in this device the stripperpush es the loop of the knot close up to the bundle and does not allow of the bundle being bound loosely. The cord is caused to enter the different notches in the looper in accordance with the presentationthat is to say, when the looper first takes the cords in the notch H Fig. 16, there is no rotation; but in the subsequent wrappings of the cord the rotations and position of the cord-holder are the fundamental agencies which govern or control the arrangement of 'the cords in the grooves. For instance, during the rotations of Figs. 17 and 18 the cord-holder is relathe looper to take the cord ends in the second groove H Fig. 19. Subsequently another shifting of the cord-holder and stripper causes the cord ends to lie in the groove H and strip the original loop over the point or hook H Figs. 12, 13, and 20. hen the cordholder I is at the lowest position or approaching that shown in Fig. 2, the cord pulls direct from the cord-holder over to the segment B. (See Fig. 1.) As the needlehead swings around to the position shown in Fig. 2, it has put considerable tension on the cord, and this pulls upon the holder I at its lower part. This action is resisted by the hinged arm J and the roller i in the cam-groove 0 Thus the cord cannot influence the position of the cord-holder in the start, and the rigidity of the cord-holder insures the cord being received in the needle-head properly.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
